sion problems are increasingly severe (Küsmenoğlu and Muehlbauer, 1998). Domestication and subsequent genetic enhancement in lentil (Lens Individual lentil plants are typically short with slender culinaris Medik.) have involved changes in plant structure and DM stems and so crop stands produce small amounts of distribution. These changes were examined using a ‘‘genetic gradient’’ comprising thr...

STUDY OBJECTIVES Obstructive sleep apnea syndrome (OSAS) is associated with impairment of cognitive function, and improvement is often noted with treatment. Golf is a sport that requires a range of cognitive skills. We evaluated the impact of nasal positive airway pressure (PAP) therapy on the handicap index (HI) of golfers with OSAS. METHODS Golfers underwent a nocturnal polysomnogram (NPSG)...

Drought is a major constraint to rice (Oryza sativa) yield and its stability in rainfed and poorly irrigated environments. Identifying genomic regions influencing the response of yield and its components to water deficits will aid in our understanding of the genetics of drought tolerance and development of more drought tolerant cultivars. Quantitative trait loci (QTL) for grain yield and its co...

The objective of this study was to evaluate the performances three cassava genotypes on yield, physiology and morphological traits under different fertilization regimes. A field experiment conducted in a split-plot design for two consecutive seasons Mansa district Luapula Province Northern Zambia highly weathered Chromi-haplic Acrisol soils. Four regimes, control-M3, lime-M1, NPK fertilizer-M4 ...

Drip irrigation can reduce water and fertilizer use; however, the frequency of topdressing required for drip wheat in Huang-Huai-Hai region is still unclear. Through two continuous season field experiments, yield related traits under traditional surface (border irrigation) three fertilization frequencies (DF2, DF3, DF4, that was, twice, or four times same way during growth period) cultivars (Ji...

Mustard is Bangladesh's leading oil crop, produced only during the winter (rabi) season. The sowing date a key factor determining mustard's optimum growth and development. Because of global warming, gradual changes in season weather parameters over time creating challenge mustard cultivation. Thus, present investigation assessed role different planting dates on several modern varieties to discl...
